Why the study?

Performing metabolic and bariatric surgery in patients with a BMI greater than 50 and 60 kg/m² has been a topic of debate.

Does metabolic and bariatric surgery have different complication rates and metabolic outcomes in patients with BMI >60 kg/m² compared to those with BMI 50-60 kg/m²?

Key Points

Postoperative complications are significantly different between patients with BMI 50–60 kg/m² and BMI > 60 kg/m² after surgery.
In the analysis, five-year metabolic outcomes were reported for patients in both BMI categories, showcasing their health trajectory.
This comparative study assesses metabolic outcomes following bariatric surgery, using patient BMI as a key differentiator.
Understanding these differences is crucial for tailoring postoperative care and improving patient outcomes.

Structured PICO

Does metabolic and bariatric surgery have different complication rates and metabolic outcomes in patients with BMI >60 kg/m² compared to those with BMI 50-60 kg/m²?

P

Population

1,430 patients aged ≥18 years with a body mass index (BMI) ≥50 kg/m² who underwent their first metabolic and bariatric surgery (MBS) between March 2016 and January 2023 at a tertiary academic hospital in Iran, with at least one year of follow-up.

I

Intervention

Metabolic and bariatric surgery (MBS) in patients with BMI >60 kg/m²

C

Comparator

Metabolic and bariatric surgery (MBS) in patients with BMI 50-60 kg/m²

O

Outcome

Postoperative complications and five-year metabolic outcomes (including suboptimal initial response, recurrent weight gain, and obesity-related condition remission)surrogate

Metabolic and bariatric surgery in patients with BMI >60 kg/m² yields similar long-term weight loss and comorbidity remission as in those with BMI 50-60 kg/m², despite higher initial ICU admission and 30-day mortality rates.

Implication

Supports MBS in BMI ≥60 kg/m² patients; extends observational evidence to super-super obesity.
